Security Bulletin
Summary
Security vulnerabilities have been discovered in OpenSSL.
Vulnerability Details
CVE-ID: CVE-2014-0160
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by an error in the TLS/DTLS heartbeat functionality. An
attacker could exploit this vulnerability to expose 64k of private memory and
retrieve secret keys. An attacker can repeatedly expose additional 64k chunks
of memory. This vulnerability can be remotely exploited, authentication is not
required and the exploit is not complex. It can be exploited on any system
(ie. server, client, agent) receiving connections using the vulnerable OpenSSL
library.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92322
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)
Warning: We strongly encourage you to take action as soon as possible as
potential implications to your environment may be more serious than indicated
by the CVSS score.
CVE-ID: CVE-2014-0076
DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive
information, caused by an implementation error in ECDSA (Elliptic Curve
Digital Signature Algorithm). An attacker could exploit this vulnerability
using the FLUSH+RELOAD cache side-channel attack to recover ECDSA nonces. This
vulnerability can only be exploited locally, authentication is not required
and the exploit is not complex. An exploit can only partially affect
confidentially, but not integrity or availability.
CVSS Base Score: 2.1
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91990
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:L/Au:N/C:P/I:N/A:N)
Affected Products and Versions
IBM SAN Volume Controller
IBM Storwize V7000
IBM Storwize V3700
IBM Storwize V3500
All products are affected when running code release V6.4.1.
Earlier code releases are unaffected.
Remediation/Fixes
For IBM SAN Volume Controller, IBM Storwize V7000, V3700 and V3500 running
6.4.1 code releases, install the following code level:
V6.4.1.9
Latest SAN Volume Controller Code
Latest Storwize V7000 Code
Latest Storwize V3700 Code
Latest Storwize V3500 Code
After applying the fix, additional instructions are needed for CVE-2014-0160
1) Replace your SSL Certificates.
You need to revoke existing SSL certificates and reissue new certificates. You
need to be sure not to generate the new certificates using the old private key
and create a new private key (ie using "openssl genrsa") and use that new
private key to create the new certificate signing request (CSR).
2) Reset User Credentials
Users of network facing applications protected by a vulnerable version of
OpenSSL should be forced to reset their passwords and should revoke any
authentication or session related cookies set prior to the time OpenSSL was
upgraded and force the user to re-authenticate.
Warning: Your environment may require additional fixes for other products,
including non-IBM products. Please replace the SSL certificates and reset the
user credentials after applying the necessary fixes to your environment.
Workarounds and Mitigations
Ensure that all users who have network access to the system are authenticated
by a security system such as a firewall.
